Wireless sensor networks (WSN) usually have limited energy and transmission capacity, which can't match the transmission of a large number of data collected by sensor nodes. So, it is necessary to perform in-network data compression in the WSN. This paper proposes an algorithm of data compression based on multiple principal component analysis (multiple-PCA), iteratively using PCA method in multiple...
In recent years, wireless sensor networks (WSN) have a wide application prospects. So it has attracted great interests in several related research fields and industries. Based on the characteristics of DV-Distance and centroid location algorithm, a novel hybrid localization algorithm based on DV-Distance and the twice-weighted centroid in wireless sensor network is proposed. The main principle of...
Based on the characteristics of DV-Distance, an improved scheme for the typical distributed localization algorithm in wireless sensor network is proposed. The main principle of the improved scheme is to introduce the hops between anchor nodes and unknown nodes to determine calibration value of the distance.Further more,a method of the new distance correction based on hops and Straight-line distance...
